Excellent running and very strong Jett .40 with Jett Black Racing Pipe. The exhaust port has been slightly raised from stock for a little more RPM. Great compression, smooth bearings, Afterun oil was always used. I emailed Dub Jett to purchase several parts along with pictures and he said this is a 426 Capps racing engine. Only Blemish is on one of the mounting holes but still works fine. See pics. This happened sometime in its previous racing history. No other issues and the crank is straight and true. You get the Engine, Pipe, spinner nut, 5 various pylon props, 4 9 std APC props, 2 brand Merlin new glow plugs and both backplate mount and standard backplate.I flew this on a Diamond Dust 160mph+ and 150+ on a Quickie 500 with 15% Omega Fuel ** This is NOT a beginner engine or for the timid** This thing is a racing engine and it scares people!! It does not Idle!! its basically all or nothing. $165+ $15 Shipping with insurance. I accept Paypal with no fees. No Warranty. Thanks, Chris
